When you pour a glass of water from your Earths Water filter, have you ever stopped to wonder how water filters work, and what’s really happening between the time water enters your filter and when it lands in your glass?

Well, you’re not just seeing clean water; you’re seeing some serious science at work. It’s not just making your water taste better (though it does that brilliantly). It’s actually a carefully designed, multi-stage process that strips away the nasties while letting the good stuff flow through.

At Earths Water, we think about this science every single day. We've spent years refining our filtration process to suit the unique challenges of Australian tap water. The result? Clean, refreshing water that tastes good enough to make you want more of it—and that means better hydration for the whole family.

Our Exclusive Water Filter Technology

Everything begins with COREtech™, our proprietary and advanced multi-stage water filter technology, designed specifically for Australian water. Think of it as the brain and backbone of every filter we create. Inside COREtech™, different types of filtration media work together, each with a role to play, to deliver water that’s cleaner, fresher, and better for you. Here’s how it works:

The First Step: Pre-Filter Mesh

Before anything else, water flows through a fine pre-filter mesh. This stage takes care of the obvious culprits—sediment, rust, dirt, and grit—the things you don’t want swirling around in your glass. It’s simple but essential, setting the stage for the more advanced filtration that follows.

Activated Carbon (Natural Coconut Shell)

The natural coconut shell activated carbon comes next—a renewable, eco-friendly material packed with millions of tiny pores. These pores act like magnets for contaminants, drawing them in and holding them tight. Backed by research from the EPA and NSF, activated carbon has been shown to:

  • Remove around 60–80 harmful chemicals

  • Reduce another 30 contaminants

  • Moderately reduce an additional 22 substances

This stage is especially effective at targeting chlorine, chlorine by-products, pesticides, herbicides, PFAS (forever chemicals), pharmaceuticals, and even microplastics. The best part? It strips away impurities while letting beneficial minerals like calcium and magnesium flow through.

Ion Exchange Resin: The Hard Water Balancer

Next, COREtech™ employs ion exchange resin. These charged beads swap out unwanted minerals and contaminants for beneficial ones. The result: softer, smoother water that removes nasties, rebalances alkalinity, and adds back helpful minerals like calcium, magnesium, and potassium. It’s good for you, and kinder on your appliances too.

The Final Polish: Micro-Particle Layer

Finally, COREtech™ finishes the job with ultra-fine layers that catch microscopic particles like sediment, dirt, and tiny impurities you can’t see. This last stage ensures your water doesn’t just look clear—it tastes crisp and fresh too.

What Earths Water Filters Are Made Of

Science is important, but so are materials. Because the last thing you want is a filter that cleans your water but adds to the planet’s problems.

At Earths Water, we build our products with care:

  • Borosilicate glass: strong, heat-resistant, and crystal-clear. Unlike regular plastics that scratch and leach, borosilicate glass keeps your water pure and looks timeless on your benchtop.

  • Natural bamboo: a renewable, biodegradable material that reflects our commitment to eco-friendly living.

  • BPA-free plastic: when we use plastic, it’s only the safe kind—durable, non-toxic, and free from harmful chemicals.

Together, these choices support our bigger vision: clean water for every living creature, without adding more waste to the planet.

Backed by Science: Certifications That Count

It’s easy to say a filter “works.” But at Earths Water, we go further. Every filter we design is tested and certified against international standards so you don’t have to take our word for it.

  • NSF (National Sanitation Foundation): Independent testing that guarantees safety and performance in water filtration.

  • LFGB (German Food Safety Standards): Ensures materials are food-safe and won’t leach harmful substances into your water.

  • ISO 9001 & BSI (Quality Management): Proof that our processes consistently deliver high-quality products, recognised worldwide.

  • RoHS & EMS (Environmental Responsibility): Guarantees our products are free from harmful substances and produced in ways that minimise environmental impact.

And we’re not stopping there. Our partnership with CSIRO, Australia’s national science agency, helps us keep improving and innovating so that your family, and future generations, get the very best in water filtration.

Earths Water Filters Built for Australian Homes

When it comes to filtering water, not every household needs the same setup. That’s why Earths Water offers a range of options, all designed to fit seamlessly into everyday Aussie life: 

2.4L Water Filter Jug

Perfect for families who want fresh, filtered water on the go. Compact enough for the fridge door, it’s an easy swap for anyone still buying bottled water. Just fill, filter, and pour.

9L Glass Benchtop Water Filter

A real centrepiece for the kitchen. Made from durable borosilicate glass with natural bamboo accents, this filter isn’t just functional, it’s beautiful too. Holding up to 9 litres, it keeps households hydrated without constant refilling.

Shower Filter

Your skin is your largest organ, and it meets water daily. Our shower filter reduces chlorine and impurities, leaving showers feeling gentler on skin and hair. It’s a small change with big comfort benefits.

Under Sink RO Water Filter

The powerhouse of filtration. Using reverse osmosis (RO) technology, our under sink filter removes even the tiniest contaminants, from heavy metals to microplastics. Ideal for households who want the purest drinking water possible, straight from the tap.

Why Earths Water Filters Stand Out

At first glance, a water filter might seem like a “nice to have”. But behind every glass of filtered water is a story—a story of chemistry, engineering, and care for both people and the planet. At Earths Water, we take that seriously. Our filters don’t just remove nasties; they’re built with sustainable materials, backed by certifications, and powered by innovative water filter technology that protects what matters most: your health, your family, and our shared environment.

So the next time you pour a glass from your jug, benchtop, or under sink filter, know this: there’s a lot happening inside that simple-looking unit. And it’s one less single-use plastic bottle, one less gulp of chlorine, and one more step towards a future where clean water isn’t just a privilege, but a right for all living creatures.
